Clear and Present Danger

Another helicopter, this one a Marine CH-53E Super Stallion, lifted off the deck of USS Guadalcanal just before dawn. It flew west over the Bay of Panama to Corezal, a small military site near the Gaillard Cut, the most difficult segment of the original Panama Canal construction project. The helicopter - carrier's flight-deck crew attached a bulky item to a sling dangling from the helicopter's underside, and the CH-53E headed awkwardly toward shore. After a twenty-minute flight, the helicopter hovered over its predetermined destination. The pilot killed his forward speed and gently eased toward the ground, coached by instructions from the crew chief, until the communications van touched down on a concrete pad. The sling was detached and the helicopter flew off at once to make room for a second aircraft, a smaller CH-46 troop carrier which deposited four men before returning to its ship. The men went immediately to work setting up the van.

The van was quite ordinary, looking most of all like a cargo container with wheels, though it was painted in the mottled green camouflage scheme of most military vehicles. That changed rapidly as the communications technicians began erecting various radio antennas, including one four-foot satellite dish. Power cables were run in from a generator vehicle already in place, and the van's air-conditioning systems were turned on to protect the communications gear, rather than the technicians. They wore military-style dress, though none of them were soldiers. All the pieces were now in place.

Or almost all. At Cape Canaveral, a Titan-IIID rocket began its final countdown. Three senior Air Force officers and half a dozen civilians watched the hundred or so technicians go through the procedure. They were unhappy. Their cargo had been bumped at the last minute for this less important one (they thought). The explanation for the change was not to their collective satisfaction, and there weren't enough launch rockets to play this sort of game. But nobody had bothered telling them what the game actually was.

"Tallyho, tallyho. I have eyeballs on target," Bronco reported. The Eagle bottomed out half a mile astern and slightly below the target. It seemed to be a four-engined Douglas. A DC-4, -6, or -7, a big one-the biggest he'd yet intercepted. Four piston engines and a single rudder made it a Douglas product, certainly older than the man who was now chasing it. Winters saw the blue flames from the exhaust ports on the big radial engines, along with the moonlight shimmering from the propellers. The rest was mainly guesswork.

The flying became harder now. He was closing on the target and had to slough off his airspeed lest he overtake it. Bronco throttled his Pratt Whitney engines back and put on some flaps to increase both lift and drag as he watched his airspeed drop to a scant two-hundred forty knots.

He matched speed when he was a hundred yards aft of the target. The heavy fighter rocked slightly - only the pilot would have noticed - from the larger plane's wake turbulence. Time. He took a deep breath and flexed his fingers once around the stick. Captain Winters switched on his powerful landing lights. They were alert, he saw. The wingtips rocked a second after his lights transfixed the former airliner in the sky.

"Aircraft in view, please identify, over," he called over the guard frequency.

It started turning - it was a DC-7B, he thought now, the last of the great piston-engine liners, so quickly brushed aside by the advent of the jetliners in the late fifties. The exhaust flames grew brighter as the pilot added power.

"Aircraft in view, you are in restricted airspace. Identify immediately, over," Bronco called next. Immediately is a word that carries a special meaning for flyers.

The DC- 7B was diving now, heading for the wave tops. The Eagle followed almost of its own accord.

"Aircraft in view, I repeat - you are in restricted airspace. Identify at once!

Turning away now, heading east for the Florida peninsula. Captain Winters eased back on the stick and armed his gun system. He checked the surface of the ocean to make sure that there were no ships or boats about.

"Aircraft in view, if you do not identify I will open fire, over." No reaction.

The hard part now was that the Eagle's gun system, once armed, did everything possible to facilitate the pilot's task of hitting the target. But they wanted him to bring one in alive, and Bronco had to concentrate to make sure he'd miss, then squeezed the trigger for a fraction of a second.

Half the rounds in the magazine were tracers, and the six-barrel cannon spat them out at a rate of almost a hundred per second. What resulted was a streak of green-yellow light that looked like one of the laser beams in a science-fiction movie, and hung for a sizable portion of infinity a bare ten yards from the DC-7B's cockpit window.

"Aircraft in view: level out and identify or you'll eat the next burst. Over."
